Mr. Declan Smyth:

A great many services are provided over the Internet by email or Zoom call and they are not monitored or even necessarily subject to any declaration. That is the nature of modern services.

Goods, on the other hand, have to be physically presented to customs. In the case of goods originating in the settlements, they are not covered by the EU's agreement with Palestine, nor are they covered by the European Union's agreement with Israel, which only applies to the territory of Israel.
